Highly optimized wireless bridges based on IEEE 802.11n are capable of high
data transfer rates even over long distances.
This chapter introduces the basic principles involved in designing point-to-
point links and provides tips on aligning the antennas.
5.3.1
Geometric dimensioning of outdoor wireless network links
The following basic questions must be answered when designing wireless
links:
Selection of antennas using the LANCOM Antenna Calculator
You can use the LANCOM Antenna Calculator to calculate the output power
of the access points as well as the achievable distances and data rates. The
program can be downloaded from our Web site at www.lancom.eu.
